Seesaw: Multiline text field not shrinking with frame

Question

I mount the following seesaw code (:require [seesaw.core :as ss]) into any frame:

(ss/scrollable
 (ss/grid-panel         
  :items [(ss/scrollable
           (ss/text
            :rows 8
            :multi-line? true
            :wrap-lines? false
            :text "this is good"))

          (ss/scrollable
           (ss/text
            :rows 8
            :multi-line? true
            :wrap-lines? true
            :text "this is bad"))]))

Both fields should scale with the frame. The second field, however, will only expand but not contract horizontally, so I keep getting horizontal scrollbars (which I don't like, see screenshot). The only difference is :wrap-lines? being set to true in the problematic case.

The problems also arises with other containers (mig-panel, vertical-panel…) the only difference being that sometimes the field expands indefinitely in horizontal direction.

Any explanations for that or ideas how to circumvent it?

Many thanks!
